New Sampling Size for Testing of Compressive Strength of Concrete

Usually 6”x12” size cylindrical samples are taken to test compressive strength of concrete. But 4”x8” sized samples are also satisfy ASTM C31/C31 M03. It is noticed that the 4”x8” sample provides some advantage. These are as follows:

1. More than three samples of 4”x8” can be made with the concrete that required for a 6”x12” cylinder sampling i.e., 70% concrete is saved.
